What are examples of simpler universes that have been described in order to explain a concept from our more complex universe?post by Mati_Roy (MathieuRoy) · 2020-09-17T01:31:10.367Z · LW · GW · 2 comments
This is a question post.
Sometimes there's a concept that can be difficult to understand when entangle with everything else that needs to be understood about our physics.
If you isolate that concept in a simpler universe, it makes it easier to explain how the concept works.
What are such examples?
(I feel like I asked a similar question somewhere at some point, but can't find it)
